HI, I get this error when I use it

[ERROR] Can't find a diff executable in PATH 
C:/Ruby30-x64/lib/ruby/gems/3.0.0/bin;C:\Program Files\ImageMagick-7.0.10-Q16-HDRI;

In the environment variable DIFFY_DIFF set "C:\Ruby30-x64\lib\lib\ruby\gems\3.0.0\gems\diffy-3.4.0\lib" or "C:\Ruby30-x64\lib\lib\ruby\gems\3.0.0\gems\diffy-3.4.0\lib\diffy" and this is what I got.

[ERROR] Can't execute diff program 'C:\Ruby30-x64\lib\ruby\gems\3.0.0\gems\diffy-3.4.0\lib\diffy'

I set these two to the system environment variable Path and it worked. it looks like I didn't set up devkit properly. Sorry for the trouble.
